Golang工具集-String工具,时间工具,http工具等 “ 避免重复造轮子 ”

gotool

======

gotool 是一个小而全的 Golang 工具集,主要是将日常开发中常用的到方法进行提炼集成,避免重复造轮子,提高工作效率,每一个方法都是作者经过工作经验,和从以往的项目中提炼出来的。

2021-7-9 更新内容详细使用请看文档


  • 添加文件 IO 操作工具 FileUtils
  • 添加验证码生成工具 CaptchaUtils
  • 添加文件目录压缩和解压缩工具 ZipUtis
  • 字符串数组工具 StrArrayUtils

如何使用 gotool 呢?

Logs 日志打印工具

===========

1、gotool.Logs.ErrorLog 异常日志

2、gotool.Logs.InfoLog 加载日志

3、gotool.Logs.DebugLog 调试日志

func TestLogs(t *testing.T) {
gotool.Logs.ErrorLog().Println("Error日志测试")
gotool.Logs.InfoLog().Println("Info日志测试")
gotool.Logs.DebugLog().Println("Debug日志测试")
}
//out

[DEBUG] 2021/07/07 15:58:10 logs_test.go:11: Debug日志测试
--- PASS: TestLogs (0.00s)
PASS

PageUtils 分页工具

1、gotool.PageUtils.Paginator 彩虹分页

func TestPage(t *testing.T) {
paginator := gotool.PageUtils.Paginator(5, 20, 500)
fmt.Println(paginator)
}
//out
== = RUN   TestPage
map[AfterPage:6 beforePage:4 currPage:5 pages:[3 4 5 6 7] totalPages:25]
--- PASS: TestPage (0.00s)
PASS
//说明 AfterPage 下一页  beforePage前一页 currPage当前页 pages页码 totalPages总页数

IdUtils

=======

id 生成工具,可生成字符串 id 和 int 类型 id,根据需要选择自己需要的生成规则

1、gotool.IdUtils.IdUUIDToTime 根据时间生成的 UUID 规则,入参 true 消除“-”false 保留“-”

func TestUUID(t *testing.T) {
time, err := gotool.IdUtils.IdUUIDToTime(true)
if err == nil {
fmt.Println("根据时间生成UUID去除--------------------->'-'----->", time)
}
time, err = gotool.IdUtils.IdUUIDToTime(false)
if err == nil {
fmt.Println("根据时间生成不去除--------------------->'-'----->", time)
}
}
//out
== = RUN   TestUUID
根据时间生成UUID去除--------------------->'-'-----> 6fb94fe4dfd511ebbc4418c04d462680
根据时间生成不去除--------------------->'-'-----> 6fb9c783-dfd5-11eb-bc44-18c04d462680
--- PASS: TestUUID (0.00s)
PASS

2、gotool.IdUtils.IdUUIDToRan 根据随机数生成的 UUID 推荐使用本方法,并发不会出现重复现象入,参 true 消除“-”false 保留“-”

 time, err := gotool.IdUtils.IdUUIDToTime(true)
if err == nil {
fmt.Println("根据时间生成UUID去除--------------------->'-'----->", time)
}
time, err = gotool.IdUtils.IdUUIDToTime(false)
if err == nil {
fmt.Println("根据时间生成不去除--------------------->'-'----->", time)
}
//out
== = RUN   TestUUID
根据随机数生成UUID去除--------------------->'-'-----> cf5bcdc585454cda95447aae186d14e6
根据随机数生成不去除--------------------->'-'-----> 72035dba-d45f-480f-b1fd-508d1e036f71
--- PASS: TestUUID (0.00s)
PASS

3、gotool.IdUtils.CreateCaptcha 生成随机数 id,int 类型,入参 int 1-18,超过 18 后会造成 int 超过长度

func TestCreateCaptcha(t *testing.T) {
captcha, err := gotool.IdUtils.CreateCaptcha(18)
if err != nil {
fmt.Println(err)
}
fmt.Println("18位------------------------------------------>", captcha)
captcha, err = gotool.IdUtils.CreateCaptcha(10)
if err != nil {
fmt.Println(err)
}
fmt.Println("10位------------------------------------------>", captcha)
}
//out
== = RUN   TestCreateCaptcha
18------------------------------------------> 492457482855750014
10------------------------------------------> 2855750014
--- PASS: TestCreateCaptcha (0.00s)
PASS

4、gotool.IdUtils.GetIdWork 根据时间戳在加以计算获取 int64 的 id 长度 16 位

func TestGetIdWork(t *testing.T) {
work := gotool.IdUtils.GetIdWork()
fmt.Println("根据时间戳在加以计算获取int64类型id-------->", work)
}
//out
== = RUN   TestGetIdWork
根据时间戳在加以计算获取int64类型id--------> 1625746675366450
--- PASS: TestGetIdWork (0.00s)
PASS

HttpUtils

=========

golang 的一个简单的“HTTP 请求”包 GET POST DELETE PUT

我们如何使用 HttpUtils?

resp, err := gotool.HttpUtils.Get("http://127.0.0.1:8000")
resp, err := gotool.HttpUtils.SetTimeout(5).Get("http://127.0.0.1:8000")
resp, err := gotool.HttpUtils.Debug(true).SetHeaders(map[string]string{}).Get("http://127.0.0.1:8000")

OR

req := gotool.HttpUtils.NewRequest()
req := gotool.HttpUtils.NewRequest().Debug(true).SetTimeout(5)
resp, err := req.Get("http://127.0.0.1:8000")
resp, err := req.Get("http://127.0.0.1:8000", nil)
resp, err := req.Get("http://127.0.0.1:8000?id=10&title=HttpRequest")
resp, err := req.Get("http://127.0.0.1:8000?id=10&title=HttpRequest", "address=beijing") 

设置请求头

req.SetHeaders(map[string]string{
	"Content-Type": "application/x-www-form-urlencoded",
	"Connection":   "keep-alive",
})

req.SetHeaders(map[string]string{
	"Source": "api",
})

设置 Cookies

req.SetCookies(map[string]string{
	"name":  "json",
	"token": "",
})

OR

gotool.HttpUtils.SetCookies(map[string]string{
	"age": "19",
}).Post()

设置超时时间

golang

req.SetTimeout(5) //default 30s

面向对象的操作模式

req := gotool.HttpUtils.NewRequest().
	Debug(true).
	SetHeaders(map[string]string{
		"Content-Type": "application/x-www-form-urlencoded",
	}).SetTimeout(5)
resp, err := req.Get("http://127.0.0.1")

resp, err := gotool.HttpUtils.NewRequest().Get("http://127.0.0.1")

GET

查询参数

resp, err := req.Get("http://127.0.0.1:8000")
resp, err := req.Get("http://127.0.0.1:8000", nil)
resp, err := req.Get("http://127.0.0.1:8000?id=10&title=HttpRequest")
resp, err := req.Get("http://127.0.0.1:8000?id=10&title=HttpRequest", "address=beijing")

OR

resp, err := gotool.HttpUtils.Get("http://127.0.0.1:8000")
resp, err := gotool.HttpUtils.Debug(true).SetHeaders(map[string]string{}).Get("http://127.0.0.1:8000")

多参数

resp, err := req.Get("http://127.0.0.1:8000?id=10&title=HttpRequest", map[string]interface{}{
	"name":  "jason",
	"score": 100,
})
defer resp.Close()

body, err := resp.Body()
if err != nil {
	return
}

return string(body)

POST

// Send nil
resp, err := gotool.HttpUtils.Post("http://127.0.0.1:8000")

// Send integer
resp, err := gotool.HttpUtils.Post("http://127.0.0.1:8000", 100)

// Send []byte
resp, err := gotool.HttpUtils.Post("http://127.0.0.1:8000", []byte("bytes data"))

// Send io.Reader
resp, err := gotool.HttpUtils.Post("http://127.0.0.1:8000", bytes.NewReader(buf []byte))
resp, err := gotool.HttpUtils.Post("http://127.0.0.1:8000", strings.NewReader("string data"))
resp, err := gotool.HttpUtils.Post("http://127.0.0.1:8000", bytes.NewBuffer(buf []byte))

// Send string
resp, err := gotool.HttpUtils.Post("http://127.0.0.1:8000", "title=github&type=1")

// Send JSON
resp, err := gotool.HttpUtils.JSON().Post("http://127.0.0.1:8000", "{\"id\":10,\"title\":\"HttpRequest\"}")

// Send map[string]interface{}{}
resp, err := req.Post("http://127.0.0.1:8000", map[string]interface{}{
"id":    10,
"title": "HttpRequest",
})
defer resp.Close()

body, err := resp.Body()
if err != nil {
return
}
return string(body)

resp, err := gotool.HttpUtils.Post("http://127.0.0.1:8000")
resp, err := gotool.HttpUtils.JSON().Post("http://127.0.0.1:8000", map[string]interface{}{"title":"github"})
resp, err := gotool.HttpUtils.Debug(true).SetHeaders(map[string]string{}).JSON().Post("http://127.0.0.1:8000","{\"title\":\"github\"}")

代理模式

proxy, err := url.Parse("http://proxyip:proxyport")
if err != nil {
	log.Println(err)
}

resp, err := gotool.HttpUtils.Proxy(http.ProxyURL(proxy)).Get("http://127.0.0.1:8000/ip")
defer resp.Close()

if err != nil {
	log.Println("Request error:%v", err.Error())
}

body, err := resp.Body()
if err != nil {
	log.Println("Get body error:%v", err.Error())
}
log.Println(string(body))

上传文件

Params: url, filename, fileinput

resp, err := req.Upload("http://127.0.0.1:8000/upload", "/root/demo.txt", "uploadFile")
body, err := resp.Body()
defer resp.Close()
if err != nil {
	return
}
return string(body)

提示模式

默认 false

req.Debug(true)

以标准输出打印:

[HttpRequest]
-------------------------------------------------------------------
Request: GET http: //127.0.0.1:8000?name=iceview&age=19&score=100
Headers: map[Content-Type:application/x-www-form-urlencoded]
Cookies: map[]
Timeout: 30s
ReqBody: map[age:19 score:100]
-------------------------------------------------------------------

JSON

Post JSON 请求

设置请求头

 req.SetHeaders(map[string]string{"Content-Type": "application/json"})

Or

req.JSON().Post("http://127.0.0.1:8000", map[string]interface{}{
	"id":    10,
	"title": "github",
})

req.JSON().Post("http://127.0.0.1:8000", "{\"title\":\"github\",\"id\":10}")

Post 请求

resp, err := req.Post("http://127.0.0.1:8000", map[string]interface{}{
	"id":    10,
	"title": "HttpRequest",
})

打印格式化的 JSON

str, err := resp.Export()
if err != nil {
	return
}

解组 JSON

var u User
err := resp.Json(&u)
if err != nil {
	return err
}

var m map[string]interface{}
err := resp.Json(&m)
if err != nil {
	return err
}
